Work schedules

A variety of work schedules are available that allow flexibility for workers and Laboratory programs.

The most popular work schedule is the "9/80"—employees work 80 hours over a nine-workday (two-week) period, with a Friday off every other week.

Talk to your manager about available options and how to select the option that is right for you.


The Lab recognizes the following paid holidays:

  • New Year's Day
  • Martin Luther King Jr. Day
  • President's Day
  • Memorial Day
  • Independence Day
  • Labor Day
  • Veteran's Day
  • Thanksgiving Day (and day after)

Full-time or part-time employees are eligible to accrue and use vacation leave. Casual employees are not eligible to accrue and use vacation leave.

Full-time employees accrue vacation as long as they are in pay status for at least one hour during a calendar week (Monday–Sunday).

Accrual rates are based on years of service, and summarized in the following chart (based on a full-time schedule).

Years of Service Monthly Accrual (hours) Annual Accrual (weeks)
0 - 10 10 3 weeks
10 - 15 12 3.6 weeks
15 - 20 14 4.2 weeks
20+ 16 4.8 weeks

Sick leave

Employees accrue sick leave starting on their first day of work at the rate of 8 hours per month (2.4 weeks per year).

Sick leave may be used for specific circumstances, including employee illness, medical appointments, and illness or death in the employee's immediate family.
